HDRtugi

HDRtugi is a term that refers to a specific visual effect or technique, often discussed in the context of digital imagery and video. It generally describes a perceived distortion or artifact that can occur when high dynamic range (HDR) imaging is applied, particularly in situations with extreme lighting differences or during fast motion. The term itself is a portmanteau, combining "HDR" with "tugi," which is not a standard English word but is understood within certain online communities and forums to denote this visual anomaly.

The effect can manifest in various ways, such as a ghosting or smearing of objects, a halo effect around bright lights, or an unnatural "pop-out" of certain details. These issues are often more noticeable on displays that are not adequately calibrated for HDR content or when the HDR processing algorithms are not optimized for the specific scene being rendered. While HDR technology aims to provide a more realistic and lifelike image by capturing a wider range of light and color, improperly implemented HDR can lead to these undesirable visual artifacts, which are colloquially termed HDRtugi. Discussions around HDRtugi often involve sharing examples, troubleshooting display settings, or critiquing the implementation of HDR in films, games, and other media.
